Originally launched in 1985, the R31 Skyline introduced a distinctive approach to the market. Available in both 4-door sedans and hardtops, the model set itself apart with its sleek design and luxurious features. However, what truly made the R31 standout was its station wagon variant, a body style that maintained luxury alongside practicality.
For fans of the era’s high-end Japanese cars, the R31 has become an icon. Among its enthusiasts, some argue, “The wagon version is the Holy Grail of the R31 family!” Its angular bodywork and rarity make it a favorite for collectors and tuners alike.
One shop dedicated to the craft of enhancing the R31’s unique charm, R31 House, took the wagon’s appeal to the next level with a custom build that screams performance while staying true to its roots.

Under the Hood: Tuned for Power
The heart of this R31 Wagon build lies in its engine. R31 House swapped the factory engine for the RB25DET, an inline-6 powerhouse that perfectly complements the car’s sporting aspirations. Several key upgrades elevate its performance, including:
- Tomei 1.2mm metal head gasket to boost engine durability.
- An R31 House original exhaust manifold combined with a TO4E turbocharger for optimized exhaust flow and sound.
- Fuel components replaced with Nismo parts, including the fuel pump and regulator, ensuring consistent delivery under pressure.
Power is controlled via a Trust e-Manage ECU, all while maintaining functionality of the airflow sensor. This setup delivers an impressive 400 horsepower with a peak boost of 1.0 bar, refined for high-rev durability and improved top-end acceleration.

Revamped Suspension and Brakes
To handle its newfound power, R31 House didn’t overlook drivetrain and suspension modifications. Key upgrades include:
- Silk Road-based coilovers for the front suspension, paired with KYB dampers and custom R31 House springs in the rear for improved handling.
- Brake system enhancements using R32 Skyline calipers and rotors up front, while the rear setup retains a drum-style system.
These changes ensure the wagon not only goes fast but also stops and corners with confidence.

Inside, the R31 wagon retains a 1980s charm, but it’s been fine-tuned for the performance enthusiast:
- A Defi boost gauge sits atop the steering column, providing vital metrics at a glance.
- The Blitz SBC-iD boost controller is mounted discreetly in front of the tachometer for ease of access.
- An elegant red leather steering wheel by Victoria adds a touch of exclusivity and Italian craftsmanship.
